You need three informations to locate documents in the stacks : its section, its call number and its availability (in stack, in storeroom or on loan).
The documents are classified by a unique call number that details their specific location in the Library's various sections (references, master, research, periodicals).
The most part of the sections are identified on the library maps.
The call number is based on one of two classification indexes: own library classification (section research) or the Dewey Decimal classification (MASTER section). To this are added the cutter number (unique), year of publication, and details like volume no., copy no., and so on.
Exemple d'une cote de la section master : 523.112 5/L36.MIL.2002
The periodicals located in the reading room do not have call numbers. Current year issues are available on display unit, the previous years are stored in archives rooms.
The periodicals located in in archives rooms are available on request.
You must check directly to see that the item is or not available on the shelf.
If you do not find the item, there is two explanations : the item has been borrowed or a user is still reading it in the library. Then you should search in the library catalogue that the library holds copies. Otherwise, you have the right to reserve the item by phone or by mail.
